BGP Considerations in NSX-T Integrated VMware Enterprise PKS

VMware Enterprise PKS supports two deployment models with respect to T0 and T1 Gateways since NSX-T version 2.5. Active-Passive T0 Gateway with a dedicated T1 Gateway per Kubernetes namespace. Active-Active T0 Gateway with a dedicated T1 Gateway per Kubernetes cluster  (NSX-T v2.5 onwards) In the first deployment model, a T1 Gateway is created for every…… Continue reading BGP Considerations in NSX-T Integrated VMware Enterprise PKS

Resizing NSX-T Edge node VMs

NSX-T Edge Nodes come in two form factors – VM and Baremetal both leveraging DPDK (Data Plane Development Kit) acceleration for faster packet processing. Deciding which form factor to use depends upon on our use case requirements and it is good to understand the workload traffic behavior and centralized services requirement before finalizing the Edge…… Continue reading Resizing NSX-T Edge node VMs

NSX-T Tier1 SR Placement and the effect on Northbound ECMP – Part 2

This is the second part of the blog series on NSX-T Tier 1 Gateway SR Construct placement and it’s influence on North-South routing and ECMP. In case you missed Part 1, you can read it here: https://vxplanet.com/2019/10/26/nsx-t-tier1-sr-placement-and-the-effect-on-northbound-ecmp-part-1/ In this article we will focus on Scenario 2 – Tier 1 Gateway with an SR Construct on…… Continue reading NSX-T Tier1 SR Placement and the effect on Northbound ECMP – Part 2

NSX-T Tier1 SR Placement and the effect on Northbound ECMP – Part 1

A Tier 1 Gateway requires an SR Construct whenever a Stateful or non-Distributed services are deployed on it. The SR construct is always instantiated on the Edge nodes in an Active-Passive mode for the Tier 1 Gateway. The presence of an SR Construct can influence the East-West routing, North-South routing and ECMP depending on the…… Continue reading NSX-T Tier1 SR Placement and the effect on Northbound ECMP – Part 1

NSX-T Single NVDS Multi-TEP Edge VM Deployment & Configuration on Host NVDS Networking

NSX-T introduced a Single NVDS Multi-TEP design for the Edge nodes in version 2.4, with recommendation to use from version 2.5 onwards. With this new design, we could now achieve better load balancing for the overlay traffic as well as have a consistent deployment model for both VM and BM edge form factors. A consistent…… Continue reading NSX-T Single NVDS Multi-TEP Edge VM Deployment & Configuration on Host NVDS Networking
